SimpleRasterConfigurator problems
---------------------------------
Key: UDIG-828
URL: http://jira.codehaus.org/browse/UDIG-828
Project: uDIG
Type: Bug
Components: style
Versions: UDIG 1.1.RC2
Environment: WMS layer from MapServer
Reporter: Vitali Diatchkov
Assigned to: Cory Horner
There are several problems with raster styles:
1) RasterViewer.get(..) returns null as a Symbolizer.. Later it leads to
impossibility to persist style by SLDTransformer and following errors to load
style:

2) Opacity value in RasterViewer is not persisted during changes of active
layer in "Layers" view.
3) This problem is more related to rendering: at the current moment the
buffered image of WMS layer is not cleared and newly loaded image is rendered
on the top of old. If the opacity value of raster style is 25% - then images
are overlapped with 75% of transparency..
